Specification of Letters Patent.

1913. Serial No. 759,987.

To all whom it may concern Be it known. that I, Davin SMITH, a citizen of the United States, residing at Cabool, in the county of Texas, State oi lrlissouri, have invented certain new and useful Tmprovenients in @iLBurners', and 1. do hereby declare the following to be a full, clear, and exact description oi? the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention is directed to improvements in oil burners, and more particularly to one adapted to be placed in the fire box of a cook stove.

The invention has for its object to provide a device of this type which is simple in construction, and one which is eiiective in operation.

A further object of the invention is to so construct a burner oi this type that the burner tubes may be adjusted toward or away from the stove lids so as to regulate the heat.

tVith these and other obj cots in view, this invention resides in the novel features of construction, formation, combination and arrangement 01 parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which Figure 1 is a side elevation of the burner. Fig. 2 is a top plan view of the same. Fig. 3 is a sectional view taken on line 3'3 of Fig. 1. Fig. 4 is a rear elevation.

Referring to the drawing the numeral 1 designates a pair of bases having rising therefrom uprights 2, the upper ends of which are provided with collars 3, the purpose of which will appear later.

Resting upon the bases 1 is a mixing tube 4, one end of which is threaded in the U- shaped coupling 5. Arranged directly above the mixing tube 1 is a burner tube 6 having formed longitudinally thereof a plurality 01 rows of alined jets 7. Que end of the burner tube 6 is threaded into the other end of the coupling 5, and has its other end threaded into one end of the U-shaped coupling 8. A second burner tube 9 is provided and has one 01" its ends threaded into other end of the coupling 8, and its other end closed by a plug 16. The burner tube 9 is also provided with a plurality of rows of alined jets 11 which extend longitudinally thereof.

A generating loop 12 is provided and has its lower branch 13 engaged in the collars 3, said branch having one end in communication with the valve casing 14 through the medium of the pipe 15.

The inner end of the valve casing 14 pro jects into the open end of the mixing tube 1 and engages the inwardly directed lugs 16 formed therein, said casing being provided with a needle valve 17, which is of the usual construction, and is operable to regulate the flow of gas generated in the loop 12 to the mixing tube 1, the proper amount of air being mixed with the gas at the open end of the mixing tube as it is projected into the casing 14.

The upper branch 18 of the generating loop 12 has connected thereto a casing 19 in which operates the needle valve 2i) to regulate the flow of oil which passes through the tube 21 which leads from a suitable tank (not shown).

By providing the couplings 5 and 8 it is obvious that-the burner tubes 6 and 9 nay be owing to their threaded connection with the couplings swung into horizontal plane with the mixing tube 4;, as indicated by dotted lines in Fig. 4, and at which time the jets will be a greater distance away from the stove lids, thus providing a burner which can be conveniently adjusted to fire boxes of different depth.

It is obvious that the burner can be used in connection with heating stoves, furnaces, boiler fire boxes, or any place wherein it is desired to substitute liquid fuel for coal.

What is claimed is An oil burner comprising a pair of bases, uprights rising from the bases, collars formed upon the upper ends of the up rights, a mixing tube supported upon the bases, a U-shaped coupling having one oi its ends connected to one end of the mixing tube, a burner tube having one of its ends connected to the other end. of the coupling, a second iii-shaped coupling having one of its ends connected to the first named burner tube, a second burner tube having one end the mixing tube, 'and means for supplying connected the other end of the second named coupling, a generating loop having one of its branches supported in the collars, a valve casing supported by the generating loop and having one end projecting into the mixing tube, a Valve for the casing for regulating the flow of gas generated in the loop into oil to said loop.

In testimony whereof, I afiix my signa ture, in the presence of two Witnesses.
